finding AND removing dead links in itunes?

So I have a few thousand songs in itunes right now, but some files and some folder of songs I have deleted or moved to a new location so now when I click on it to play it it comes up with a screen that says "would you like to try to locate this file?"

Is there a script that can automatically search all my drives for that song to locate it on its own?

Thats really just a backup idea as what I really want to do is have it go through and remove all the dead links. I saw one script on the forums after i searched but it sounded like it would just pull those songs with exclamation points next to them (songs that it 'realizes' are dead). My issue is I dont want to have to click on every file in itunes and click "no dont locate" to get the exclamation in the first place.....is there a script that can find out on its own if the link is dead?

thanks
